Offices not yet “in the loop” may not be aware of the many benefits that competitors have experienced after becoming a part of this consumer-driven movement.
To benefit from the increasing number of properly installed loops, worldwide (one that meet IEC 60118-4), consumers need access to a vertical telecoil with a frequency response that closely matches the microphone sensitivity at equal input levels for the speech frequencies (70 dB SPL vs 100 mA/m inputs)—something called transparency.
In his WSJ article, titled “A Technological Godsend to Counter Hearing Loss,” David Myers recounts his first experience using a hearing loop to magnetically transmit sound via a PA system to the telecoils in his hearing aids—instantly allowing him to hear a presenter’s voice with greater clarity.
